Hittest Not Working!!!!!!!!!!!

[hopies]

Hey..

I have a duplicating movieclip (acting as bullets) that shoot across the screen from a turret blah blah blah.. Their names are set as "bullet"+bulletcount; and everytime one is shot bullet++; and the result is many bullets called bullet1, bullet2, bullet3, bullet4 etc etc..

how do i get this to hit my wall i used the code

onEnterFrame = function() {
if ("bullet"+bulletcount.hitTest(_root.wall)) {
trace("hit")
}
}

However my code is not called as the bullets will pass straight over the wall and the code is called as soon as you fire the bullet....Why

Any help is appreciated..
